HOUSING FOB RDLLER-STRAIGHTENING PRESSES.

This invention relates tohousings for roller straightening presses, andmore pari ticularly to housings adapted to support the revolublestraightening rolls of the press;

The object of my invention is to provide housings for rolls and toconstruct the housings whereby the rolls can be easily removed,

repaired and renewed, without moving the housings suppkirting the rolls.

In a straightening pressit has been the l f iractice to employ housingsfor supporting the straightening rolls, and these housings have beenconstructed whereby it has been necessary for one of the housings to be;1 moved and the parts thereof disassembled in order that certain rollscould be removed `from the housings. This operation of disiiiantling therolls not only consumed considerablo time, but required a great deal oflabor and acessation in the operation of, a i

mill, which not only reduces the output but is detrimental to theproduct on account of the time that expires between the heating of theproduct or billet and the rolling opera tion to which t-lie saine issubjected.

My invention -aims to, obviate the necessity of moving a housing inorder. to remove the roll, and to this end, I have devised housings thatcan be permanently anchored,

i and in wniiect'ion with each housing, I furnish means that will allowthe rolls thereof hohe expeditiously removed with little labor,

and either repaired or. new rolls installed.

My 'invention will be hereinafter con-v f sidered in detail and thenclaimed, and reference will now be had to the drawings forming apart ofthis specification wherein there .is .illustrated a preferred embodimentof the invention', but it is to be understood that the structuralelements thereof'can be .varied or changed, as to the size, shape andmanner of assemblage, withoutl departing from the spirit and scope-ofthe invention. In the drawings: Figure 1 is a side elevation-.of a pressconstructed in accordance withmy invention.

Fig. l is an end view ofthe same. is an enlarged elevation of a portionof one of the housings. Fig. 6' is `a vertical sectional view of thesame-taken on the line :r-m of Fig. 5. Fig. 7 is a horizontal sectionalview of a portion' of the housing, and Fig. 8 is a perspective view of adetached insert plate.

In the accompanying drawings the reference numeral 1 denotes alfoundationfor a bed plate 2 and mounted uponsaid bed plate byscrew-bolts 3 are the fett 4 of housings 5,

said housings bei C( arranged'in parallelism to support -revolu lestraightening rollers adapted to provide a pass through .which is fedthe' product tobe straightened by the press. The housings are identicalin construction andv for the sake of brevity in describing my invention,I" deem it only necof one of the said housings, afterwhich the housingswill be considered as contributing' to certain results vproduced by theentire press.

Each I housing comprises -a substantial' body and the body a shortdistance above the foot 4 is reduced by inclining the end walls 6thereof inwardly Aand then carrying the walls upwardly,. as at 7 to formthe kupper end of the housing, the top of the housing being of 'a lesslength than-the bot; tom thereof owing to the fact that the upper part.of thehousing supports a less number Fig.

essary to enter into the detail construction of rolls than the bottompart of the housing.

The top part of the housingv is provided with a plurality of verticalwindows, preferably i three in numberV and designated 8 and 9, with thewindow 9 intermediate the windows 8 and of a greater depth than saidwindows,

in order that the intermediate upper roll can beadjusted relatively toother rolls located between the housings of the press. The windows 8 and9 have the upper endsI thereof open at the upper part'of the housing andthe lower end of the window 9 is closed, while the lower ends of thewindows 8 ter- 'minato in transverse polygonal openingslO vadapted tocontain the bearingsof the upper lloV 38 of upper rol s 39. The bearingblocks mus ofthe pressi. The sans of the auxiliary windows 11 arerovided with longitudinal grooves 12 a a ted to receive the tongues13.0f bearing b ocks 14, said bearing blocks having the confrontingfaces thereof provided with bushings 15 adapted to sup` portthe necks 16of the lower rolls 17 T he 'lower ends of the auxiliary windows are lV4provided with key-ways' 18v adapted to re- '12o ceive keys 19 employedfor adjusting the lower hearing blocks 14.

, y 'In the openings 10 are tted polygonalshaped retaining heads 2O andthe angularlydisposed sides 21 of these heads are adaptedl to retain theuppermost bearing blocks A14 in engagement'with the necks 16 of therolls 'l 17. The heads 2O are retained in place by plates 21counter-sunk and suitably secured, as by screws or 'other fasteningmeans 22 in the outer sides of the housings, these plates extendingupwardly to engage in recesses 23 y provided therefor in the outer facesof the heads 20. The upper edges of said heads are retained in positionby `hold-fast devices adapted to'engage partly in the heads 20 andpartlyv in the walls of the openings 10.

The inner side of the housing is recessed, as at 24, to receive aninsert'plate 25, and this plate inconjunction with the wall otI theopening 10 is cut away, as at 26, to receive a vtapering key 27,rectangular in cross I 4ov y,sect-ion', and having the smaller endthereof the head 20 within the opening 10. The insert' plates25 areprovlded whereby they can be easily renewed and thereby compensate forany wear to which the same are sub-,1

jected by the action of the tapering keys 27.

The upper reduced end of the housing is provided with a cap 30 securedto the housing by tie-rods 31 and nuts 32, said tie-rods Y having theheads thereof counter-sunk in the cap with the lower ends thereofextending 1 through lugs 33, carried by the sidesof the housing, thenuts 32 engaging said lugs to bind the cap upon the housing.

' Loosely mounted in the capv 30 at the windows 8 and 9 are screws 34and loosely connected to the lower ends of said screws 34 are hearingblocks 35 and 36 provided with bushlngs 37 ada ted to support the necks36 are adjusted relatively to the bearing blocks 35 by bolts 40 and nuts41. The upperends of the screws 34 are provided vwith horizontal gearwheels 42, said gear wheels atively to the rolls 17.

esa/,eea

'when they are rotated the screws will be raised and lowered to adjustt-he rolls. 39 rel- The gear wheels 42 mesh with worms 43 carried bytransverse shafts 44, journaled in bearings 45, carried by the caps 30of the housings, the4 end of each shaft being provided with a hand-wheel46, whereby the sha-ft can be easily rotated to adjust the rolls 3). Thehousings 5 are adapted to be connected by tiebolts or rods '47 and nuts48, these tie-rods or bolts bcing suitably disposed to rigidly supportthe housings with relation to each other.v

' It is through the medium of the angularlydisposed auxiliary windows l1and the dctachable heads 20 that I am enabled torcmove .the lower rollswithout moving either of the housings, it being only necessary to removethe heads and raise the lowermost rolls into the openings 10 and thenwithdraw the.

rolls from said openings. I do not care to confine myself to theadjustment of the bearing blocks of either the upper'rolls or the lowerrolls, to the means of securing the heads 2O in the openings 10, or tothe exact sha e of the housings and the windows thereo What I claim, is:

1. A housing for a roll straightening press, a pair of housings eachprovided with a plurality of main windows, each of which terminates atits lower end in an enlarged polygonal-shaped opening having the lowerangular sides thereof communicating with angularly-disposed rectangularauxiliary windows, certain of-thewalls of said auxiliary Windows beingprovided with grooves, one of the walls of .each of said auxiliarywindows being provided with key-ways, adjustable bearing blocks mountedin said auxiliary windows and provided with tongues engaging in saidgrooves, keys mounted in said key-ways -and engaging in said bearingsfor connecting them in position, Vsaid bearing blocks capable of beingremoved from said auxiliary windows and through said openings, andadjustable bearing blocks arranged within said main windows.

2. A housing for a roll strai htening press, a pair of housings eachprovi ed with a plurality of main windows, each of which terminates atits lower end in an enlarged polygonal-shaped opening having the lowerangular sides thereof communicating with angularly -disposed rectangularauxiliary windows, certain of the walls of said auxiliary windows beingprovided with grooves, one of the walls of each of said auxiliarywindows being provided with key-ways, adjustable bearing blocks` mountedin said auxiliary windows and provided with ton es engaging in saidgrooves, keys mounte in said key-ways and engaging insaid bearings forconnecting them in positiqn,l said bearbea-ring blocks. i
